I don’t really think there is a way to perceive others without judging or categorizing them. I do think it is possible to realize you are doing so and put yourself in check a little bit. I think it’s human nature to judge—we judge the good and the bad all the time.
Judging people’s character isn’t always bad. When you walk down a dark street and you judge the creepy looking fella’ who’s following you, you’re using your instincts to tell you to be aware of your surroundings and use them to protect yourself.
When we use our judgments to assume that a customer at work is poor and not going to buy anything so we shouldn’t bother to help them, then we aren’t really doing right.
To make things “fair,” we need to just keep in mind what categories we are putting people in and then we need to make sure that we allow people to change our minds. Maybe that guy who was following you saw that you dropped your keys and he was trying to give them back—so you can be cautious but leave your mind open to change.
